@Suty Thank you! I will make sure to clearly show the attribution everywhere you mentioned. To confirm the rest: the data stays inside the app. We don't expose it through an API of our own, we only fetch a station when a user actually opens it, so there's no background scanning of the network and no bulk history downloads.
If a provider stops sharing or asks for deletion, we can delete their cached data on our side.
Thanks for the quick and clear answer, that's everything I needed. Best, Nick
